Hi,
Tried your script, to fix perl issue but still getting errors:

I have always been in branch testing, recently after the update I received the error XCRYPT_2.0 'not found and relative KP on boot.
I recovered a previous backup with rsync but running your script and do apt update I always get the above error and KP on boot.
Is there any way to fix the error?
kind regards
Hey, thx for your feedback. @HazMatt69 @famarm
I could not solve the problem yet either.
Through the log script and further bug reports I have managed an approximation. With some bullseye-container diffs I could find the following fix for me.
- I upgrade the system as root only (
sudowon't work because it can break while upgrade!) - I test the runtime with
perl -v- ok -> done
- error -> next step
- I checked my installation of libcrypt:
ll /lib64/libcrypt.so.1=> links tolibcrypt.so.1-> links tolibcrypt-2.19.so libcrypt-2.19.sois wrong! bullseye runlibc-2.31-> delete the linkrm /lib64/libcrypt.so.1- adapt the link
ln -s /lib/x86_64-linux-gnu/libcrypt.so.1 /lib64/libcrypt.so.1 - test again
perl -v-> it works! - test sudo
sudo su-> it works! => done
Maybe this will help you
Here the repair steps as script.
- upgrade the system as root only (sudo won't work because it can break while upgrade!)
- if you saw an error while update
- something like this
Processing triggers for initramfs-tools (0.140) ... /usr/bin/perl: /lib64/libcrypt.so.1: version `XCRYPT_2.0' not found (required by /usr/bin/perl) /usr/bin/perl: /lib64/libcrypt.so.1: version `XCRYPT_2.0' not found (required by /usr/bin/perl) dpkg: error processing package initramfs-tools (--configure): installed initramfs-tools package post-installation script subprocess returned error exit status 1 Errors were encountered while processing: initramfs-tools E: Sub-process /usr/bin/dpkg returned an error code (1)
- something like this
- run the following script
#!/bin/bash rm /lib64/libcrypt.so.1 ln -s /lib/x86_64-linux-gnu/libcrypt.so.1 /lib64/libcrypt.so.1 # shows your current perl version -> system ok perl -v >/dev/null && echo "[ OK ] libcrypt spot is correct" || echo "[ERR!] libcrypt spot seems not correct (can't run perl -v) don't logout root-shell"
edit: add echo to perl -v-call
Sorry but the solution you wrote did not solve for me.
I keep getting the error after the update and go to KP.
I have to restore with rsync to have a bootable system again.
@famarm I'm sorry about that, but good thing you have a backup of the pre-situation.
My system runs clean with this workaround but I run the following cli loop til apt says "nothing to do":
apt upgrade -yqbash repair-libcrypt-v2.sh
Overall, though, this is a really terrible situation. Yes, it is testing, but I would have thought that the kind of bugs are found between unstable and testing.
Let's see how to support the community process in the future.
Good luck too you
After spending even more time on this issue, I found a simple way of fixing all the lib related issues that pop up during the upgrade, since there is a bunch.
Simply install usrmerge, modify the script to remove the files located in the /usr directories when it errors, run till it's finally happy and run the upgrade afterwards. Just works.
Update: I need to log this problematic packages, so i implement a simple log script: https://gist.github.com/deeagle/6ee1129a4e893d04c9ee98e69a7e0839
